Former President Barack Obama and his vice president, Joe Biden, will not only be immortalized in the history books, but on the internet, as memes.

Memes depicting the close relationship between Biden and Obama have been shared all over social media, and he's confirmed to NBC News that he's seen them and said many reflect his relationship with the former president.

"In essence...all true," Biden told NBC News' Savannah Sellers. "A couple of ones I liked were ones where I was trying on Ray Bans and he's lying on the couch and I turn around and I said, 'Which ones do you like?' And he looks at me and says, 'Joe, Joe, come on, focus here.'"

Biden is promoting his new book, "Promise me, Dad: A Year of Hope, Hardship, and Purpose," which talks about his son's death from brain cancer.
